The data on this
page has been collected from a combination of sources - both
from Panosaurus users and other internet resources.
Currently no camera or lens maker provides this sort of
technical data, so NONE of these
measurements can be confirmed as being completely accurate.
You should consider these numbers as possibly good starting
places to begin a manual calibration of your Panosaurus or
Panosaurus Rex.
